What is the difference between adding wax emulsion and wax powder to water-based ink? Various low-molecular, high-melting-point wax powders or wax emulsions are often added to the formulas of water-based ink coatings. The main purpose is to improve the coating surface during the thermal transfer process to have a full feel, wear resistance, scratch resistance and matting. Degassing and texturing effects.
In the water-based ink formula, the difference between adding wax emulsion and wax powder: In the water-based ink system, the role of wax emulsion and wax powder are the same, and both can It can greatly improve the wear resistance, scratch resistance, leveling and degassing of the ink film, but I think the biggest difference is the issue of dispersion and compatibility.
1. Dispersion. After the wax emulsion is emulsified with an emulsifier, the system is relatively stable and has good dispersion. When added to the ink system, it can be well and evenly dispersed in the ink system and has good compatibility. The wax powder itself is an ultra-fine particle. The finer the wax powder is added, the wax powder will agglomerate due to the action of molecular forces and is added to the ink system. If the dispersion is not good, the surface of the ink film will be rough and not smooth. The feel is grainy. But if the wax powder has good dispersion, the effect will be great.
2. Compatibility. In preparing all coating formulas, the overall compatibility will directly affect the performance of the entire product. Therefore, whether it is wax powder or wax emulsion, during use, you need to consider whether other formulas in the formula will interact with it. reaction, leading to poor compatibility issues.
In summary, in water-based ink formulations, both wax emulsion and wax powder can bring excellent product performance to the ink coating, but they must be fully Customer service dispersion and compatibility issues.
